PETA Regulatory Testing , PETA

The following comments are submitted on behalf of the more than 1.4 million members and supporters of People for the Ethical Treatment of Animals (PETA) and the Physicians Committee for Responsible Medicine (PCRM) in response to the nominations of substances to NTP for study in 2007 (March 29, 2007; Federal Register 72(60):14816-14818). PETA and PCRM are committed to using the best available sc...

Peta-Scale Computing

In a few short years, computers capable of over one Petaflops performance will become a reality. The most likely approach for first successfully reaching this performance level will involve several thousands of parallel processing elements. What are the key considerations for building such systems? What are the software requirements and demands? How will applications scale? How reliable are the...

PETA continues to claw at Columbia scientists.

Developing Peta-scalable Algorithms for Beam Dynamic Simulations*

Peta-scalable software packages for beam dynamic simulations are being developed and used at Argonne national laboratory. The standard Particle-In-Cell (PIC) method and direct Vlasov solvers in up to 4 dimensions have been developed and benchmarked with respect to each other. Both of them have successfully run on 32 thousands processors on BG/P at Argonne Leadership Computing Facility. Peta-sca...

Numerical strategies towards peta-scale simulations of nanoelectronics devices

We address two challenges with the development of next-generation nanotransistors, (i) the capability of modeling realistically extended structures on an atomistic basis and (ii) predictive simulations that are faster and cheaper than experiments. We have developed a multi-dimensional, quantum transport solver, OMEN, towards these goals. To approach the peta-scale, the calculation of the open b...
